To all 'whom ma'g concern Be it known that I, Canny A. Cnnsninn, acitizen of the United States, and a resident of the city of Chicago,county of Cook, and

State of Illinois, have invented certain new and useful Improvements inBook Gathering and Stacking Machines, of which the following is aspecification.

My invention relates to improvements in stacking and signature gatheringmachines, and has for its object the provision of an improved-machine ofthis character which is uniform in action, capable of operation atcomparatively high speed, and which arranges the gathered boolis inconvenient relation for-bundling or stitching.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanvingdrawings forming a part of this specincation, and in which,

The preferred form of construction as illustrated in the drawingscomprises a conveyer table 30 having longitudinal slots 31 therein. Feedchains are arranged under table 30 and pass over sprockets 33 and 34arranged on shafts 3 and 36 at the front and rear ends of the machine,as shown in Figs. 2, 3, 20 and E21. .Shaft is the main' shaft all, asshown in Fig. 1. Shaft i1 car ries a 43 on the shaft of an electricmotor 44. Chains 39 carry conveyor pins 45 which project upwirdlythrough slots 81 in table 30 and serve to push gathered books alongtable 30. The gathered books are placed upon table 30 by gatheringmechanism arranged at each side thereof, as will more fu ly 323M333hereinafter. BY this arrange ment it will he observed, that upon operw'tion of motor is, chains 32 will be operated to cause pins 46 to pushthe books along table 30, and that hy'loosening one ofthe gears 39 or al) on shaft ii and securing the other thereto, the speed of operation ofthe machine he changed when desired.

In order to free the gathered books free the domination of plus it? andthus permit of the passage oi said pins dowzwardly through the. end oftable 30, I n'angze a worm wheel 42 meshing with a worm for longitudinaladjustment on a bar i8 which is pivoted at its. rear end to a block 49slidable in guides 50 on the under side of table 30. At its forward endbar 48 is -mounted to slide between rollers 51 andBQ arranged in ahousing 53 on the forward end of a lever 54 which is pivoted at 55 inthe frame "of the machine, as shown in Fig. 16. The forward end of lever54 is normally heldin depressed position by a spring 56 and the rear endthereof runs upon a cam 57 fixed to a shaft 58. .-\s'shown in Figs. 1and 4, shaft 58 is provided at each end with a bevel gear 59 and isdriven by means of a-sprocket chain 60 from the main drivin shaft 35.Guide )ins 61 arran ed at the forward end of table 30.se'rve to '45 andthe passage downwardly of said guide and steady the motions of bar 48and lever 54, as will be readily understood. A link 62 connects block 49with the upper end 'of an oscillatory lever 63 whichis given-aslot andpin connection 64 with a rod 65 carried by an eccentric strap (36 onshaft By this arrangement, it will be observed,

' that upon rotation of shaft 58, pin 47 will be projected upwardlythrough slot 46, then moved forwardly at a rate of speed greater thanpins 45, then be depressedtln-ough slot 46 and returned to initialposition- The parts are. so arranged and designed that, after each pairof pins 45 passes the position of pin 47, indicated in Fig. 3, this monof pin 47 takes place thus forcing each t1 go hered book away from thecorresponding "pins 45' and leaving pins 45 free to pass downwardlythrough slots 31, as they pass around sprockets 33. The end or table 30at and immediately adjacent slot 46 is given a slight. upwardinclination whi(ah-facilitates the removal of the gathered books frompins pins through said slots.

Immediately beyond slot 46 is provided a receiving table 67 which ishorizontal and forms a continuation'of the end of table 30 so' that theby pin 47 will, beplaced on said receiving table. Thistable is providedwith an adjustable gage or positioning plate (38 against which thegathered books will be placed .and positioned by. the action of pin 47,as

will be readily understood. Table (37 is provided with transverse slots(39 extending the full width thereof, and a delivery plate pairs of pins7 72- projecting upwardly through slots 69 as best shown in Figs. 14-

and 15. Plate 70 is reciprocated by means of a lever 73 having a slotand pin connection 74 with the under side. of said plate. As shown'inFigs. 3 and l4,'the lower end oflever is pivoted on a stud 75 rigidlyfixed to at boss 76 on a cross bar of the frame of the machine. Lever 73is given a slot.

gathered book moved forwardly 0 is arranged to reciprocate under table?67 on a bar 7 land is provided with two and pin connection 77 with avertical arm 78 on the forward end of a rearwardly extending horizontalarm 79. At iis rear end,

arm 79 is fixed to a sleeve 80' which is slidably mounted on a. rod 81arranged transversely of the machine. As shown in Figs. Hand 17, sleeve80 also carries a roller 82 operating in a cam slot 83 in a drum 84fixed at the inner end of one of a pair of operating shafts 85 arrangedat each side of table (57. Each of the shafts 85 is driven by means of agear 86 meshing with an intermediate gear 87, which in turn meshes witha driving gear 88 on shaft35, asshown in Fig. arm 79 carries at itsforward end a depending arm 89 provided with a guide-way- 90 running ona stud 91' projecting from stud 75. By this arrangement, it will be ob-.served, that upon rotation of drum 84, level- 73 will 'be caused toreciprocate plate v70 and consequently pins 72. The parts are so.

arranged and timed .thateach gathered book is'positioned on table 67while pins 72 are atone terminus of their movement so that on the nextmovement of said pins, one pair thereof will contact with thecorresponding, endof the positioned book and push said book laterallyfrom table (57. Thus, at eachreciprocation of plate 70, a gathered bookwill be pushed from one side or tife other of table (37 by one or theother sets of pins 7 2.

As shown in Figs? 1 and 2, a tiltable platform 92 is arranged ateachside of table 67 in position to receive the gathered books As shownin Fig. 3,

pushed from said table. as explained above and an ad ustabIe gage 92 isarranged on each platform to liinit the movement of a book thereon.Eaelrof these platforms is carried by a rocking 'shaft 93 suitablymounted-in the frame of the machine and carrying a pinipn 94 at itsouter end. Pin-- ion 9-hmeshes with a rocking member wlnch is providedat ts upper edge with a set of gear teeth 90 ad acent each endthereofand. adapted to mesh with the correspond-.

'ing pinion 9i at each end "of the rocking movement thereof. At itslower endeach of the rocking members 9Bcarries a depending arm 97 whichis connected, as shown in Fig. 4, by means of'a link98 with a crankpin'99 on the side of a gear 100 driven from a gear 101 on shaft 85. fBy -this arrangement it will be observed that the rocking members 95will be continuously rockedor reciproc'ated and that at the end of eachmovement, gear 94 will be engaged by the corresponding gear teeth 96 andthe corre- I spending platform 92 rocked or tilted into a verticalposition to permit of the discharge of a gathered: book thereon. Thedifir'er'ent 'gears- 100 are sopositioned relatively to each other thaterank pins 99 will" u 0 be timed 90 degrees apart ,so thatrocking on theother side, but said bars are identical cated at their lower ends.

ated by means of a lever 132 having a slot.

troughs 125 is equipped with a reciprocating pusher head 1% carryingpusher bars 127 on its operative face. As shown in Fig; 5

each of the heads 126 is connected by means of a'link 128 with a-crankpin 129 formed on'the eorrespondin shaft 85, the crank pins on theopposite shafts being positioned 90 degrees apart so as to causeoperation of the corresponding pusher head immediately after eachgathered bookis deposited in Said trough. A plurality-of holding pins130 are arranged to reciprocate vertically through the bottom of each ofthe troughs 125, said pins being set to register with the spaces betweenbars 127 'and all being eon nected-together by means of a bar 131 lo-Bar 131 is oper and pin connection atone end therewith and beingprovided at its other end with a roller 133 riding upon cam 131 on shaft85.

Lever 132 is normally held in position with .pins 130 projectingupwardly into trough .125, said pins and the corresponding pusher head12( being positioned so that each discharged gathered book will fallbetween them. A slidable weighted partition 136 is arranged in each ofthe troughs 125 to constitute a support for one end of a stack ofgathered books therein. The parts are so timed and arranged thatinin'iediately after a book falls between pins 130 and bars 127, saidpins are depressed by the action of cam 13+ and pusher head 126 pushedforwardly to force said book beyond said pins whereupon pins 130 areprojected upwardly v in the space between bars 127 to hold said book inits advanced position. Then said pusher head is withdrawn rearwardly toreceive the next book and push it forward in like manner. Thus, it willbe observed that the books deposited in the respective troughs 125 willbe pushed therethrough on'their edges in convenient relation andposition for bundling or for stitching, and may be readily removed fromsaid troughs for such ;perations, or, if desired, permitted to feedautomatically from the end of said troughs onto any suitable support orinto any desired additional machinery.

The mechanism which. gathers the books upon table 30 in front of, feed pns 45 is therein.

illustrated in Figs. 20 to 28 inclusive of the drawings. This mechanismis the same in general construction and plan of operation as thatdisclosed in my prior application, Serial No. 771,003, filed May 31st,1913, some minor improvements, having been 'made Atjeach side of therear end of table 30 I mount a bar 13?. upon bearings 138 whichreciprocate upon transverse guide I rods 139, the barat the right handside of the machine as illustrated in'Fig. 2}, being arranged at ahigher elevation than the bar in operation. Said bars are set inrecesses 110 in the upper sides of bearings 138 and slats 141 aresecured centrally to the upwardly projecting ends of each of saidbearings, as indicated in F ig. 23. Bars 142 are secured to the ends. ofslats 1-11 and other slats 143 are secured to said bars parallel withslats 111. Side bars 141 are hinged to the ends of bars 1&2 and slats145 are secured to bars 1%, all of said slats being distanced slightlyapart so as to form longitudinal slots 146 in the supporting surfacethus provided. The bearings 138 are arranged on opposite sides of table30 in transversely alining pairs, one of said bearings, and consequentlyone of said supporting surfaces being provided for each signatureof thebook to be gathered, as will be readily understood. Adjustably securedin each of the slots 146 is a T-bar 117 which, as shown in Figs. 27and'29 is provided with a flange 14S bearing against the under sides ofthe adjacent slats. At their outer ends each of the bars 147 areprovided with flanges 119 taking over the tops of the adjacent bars soas to retain said bars in said slots. A headed stop screw 150 isthreaded through each of the bars 117 adjacent its operative end and abinding screw 151-is passed loosely vthrough the end of each of. saidbars adjacent screw 150. The flange portion of the bar is removed atthis point and a binding plate 152 is substituted therefor and isthreaded upon each of the screws 150 and 151. By this arrangement, itwill be observed that screws 150 may be adjusted to difi'erentelevations so as to adapt them to engage articles of dilferentthicknesses resting on the slats 141, 113 and 115 and that said screwsand bars 117 may be tightly bound in adjusted positions between slats145 by tightening the corresponding screw 151. An opening 153 is formedin each of the bars 11*? adjacent the inner edge of screw 150 to permitthe passage of any lint or dirt removed by said screws. As shown in-Figs. 22 and 21 a projection 151 is secured centrally to each of theouter slats H5 and an adjusting rod 155 is hingedly connected thereto.Rod155 slidesfreely. through bar the different signatures of the book.

rear of each of the feed hoppers is formed by means of aI'Od'157-Wl11Cll is transversely slidable' in a bracket 158 secured tothe frame The of the machine below the hopper, and said means of a setscrew 159. As shown in 23, at inner end, each of the rods 15? is bentupwardly and then downwardly at 160 to form t e outer end of the hopperand carries a cross bar 181 extending transversely across the outer endthereof. As shown in Fig. 22 the sides of each of the hoppers are formedby an angular rod 162 having one portion set vertically. and itshorizontal portion extending through a cross head 163 Where it isadjustably secured by means of a set screw 164.. Head 163 is carried bya depending rod165 which is vertically slidable on the corresponding bar187 and is rendered adjustable by means of set screw 166. At its lowerend each of the rods 162 carries a cross bar 167 constitilting thecorresponding side of the corresponding hoppcr. It will be observed thatthe outer end and sides of each of the hoppers are formed by memberssupported from below thus leaving these portions of the hoppercomparatively free and unobstructed for the insertion and straighteningof the signatures therein. The inner or feed side of each of the hoppersis formed by a ver' ically sliding bar 168 sliding in guides 169 andcarrying an arm 170 which is threaded upon an adjusting screw 171supported in a bar 172 extending along the corresponding portion of allof the hoppers of the same side oi the machine. By this arrangement, itwill be observed, that the stop bar 168 may be nicely adjusted to permitthe passage of the bottommost signature of the pile in each of thehoppers.

As shown in Fig. 21, each of the bars 137 carries at'each of its ends apivotal block 17 3 engaging a slot in the upper end of a rock- .inglever 17%, the lower end of said lever being-slotted to engage aneccentric cam 175 fixed to a shaft 176., each of the shafts 176 beingdriven at its forward end by means of a bevel gear 176 engaging bevelgear 59 on shaft 58, as shown in Fig. 1. The cams 175 on opposite sidesof the machine are so set as to cause simultaneous reciprocations oi thebars 137 and consequently corresponding reciprocation of the bottoms ofthe various hoppers.

Each of the hopper supports is provided with a centrally inwardlvextending narrow supporting finger 177 adapted to pass between two pairsof feed rollers 178 so as hopper,

to support the corresponding portion of a signature being fed to saidfeed rollers. By this arrangement it will be observed that at eachreciprocation of the-botto1n plate of each the bottommost signature willbe delivered to the corresponding feed rollers, and'thus withdrawn fromthe hopper and deposited on table 30, the rcciprocations of said platesbeing so timed relatively to the speed of travel of chains 32, that thedifferent signatures will be properly deposited one on top of the otherin front of the corresponding pins 45. mounted respectively on a shaft179 extending the full length of the hoppers and the counter-shaft 180connected therewith by means of gears 181. Each of the shafts 179 isdriven by means of a sprocket chain 182 from the corresponding shaft 176as shown in 21. Each of the shafts 179 is also provided with a handwheel 183 by'means Feed rollers 178 are of which the same may bemanipulated by hand if desired.

As shown in Fig. 21, lateral positioning plates or bars 184 are arrangedon each side f table 30 opposite the feed hopp rs and provided withupwardly extending guide fingers 1.85 adapted to facilitate the depositof signatures therebe'tween. At intervals each of the'bars 181 carrydownwardly extending guide projections 186 operating in correspondinggrooves 187 in the top of table 30, as shown in 22. As shown in Fig. 26,each of the bars 184: are connected-by means of rods 188 with the underside of a bar 189 arranged to reciprocate at the corresponding side ofthe machine in guides 189. Set screws 190 serve to adjust the positionof rods 188 and consequently the bars 184. Each of the bars 189 isconnected by means of pivoted links 191 with the blocks 192. pivotallyconnected with "theupper ends oirockcr levers 198 which are slotted attheir lower ends and engaged with eccentric cams 194 mounted on thecorresponding shaft 17 6. Each of the levers 193 is. mounted upon a studbolt mama ment, it willbe Observed that the bars 184.

will be recip'rocated inwardly and out; wardly to laterally position orjog the endsof the book signatures to keep the same in nice registrationwith each other. By this arrangement, it will by Observed that the booksignatures may be readily gathered in piles to form a complete book andthat these piles will be pushed along table 30 by fin-' gers lo andremoved therefrom, as explained above. I justable guides 197 areprovided on table liongitudinally and laterally ad- 30 beyondpositioning bars 184 so as to maintain the gathered books in properposition during their travel over this portion of table 30. I

l/Vhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit oftheinvention. I, therefore, do not wish to be limited to
